Connecting a USB flash drive to a Huawei switch

To use a USB flash drive with a Huawei switch, format it as FAT32, include the required index and upgrade files, and connect it to the switch's USB port, preferably the master switch in a stack.Preparing the USB Flash DriveFormat the drive: Use FAT32 to ensure compatibility with Huawei switches .Add required files: Place the smart_config.ini index file in the root directory of the USB drive. Include any system software files (.cc) and optional configuration files (.cfg or .zip) as specified in the index file .Security considerations: For configuration files, it is recommended to use smart_config.ini with encryption and HMAC check to enhance security .Connecting to the SwitchSingle switch: Insert the USB flash drive into the switch's USB port. The switch will automatically read the index file and start the upgrade or deployment process .Stacked switches: Connect the USB drive only to the master switch. Connecting to a standby or slave switch will prevent the deployment process from starting .Indicators: During deployment, the SYS LED may blink rapidly. Once the process completes, the LED will return to a slow blink, indicating the upgrade is finished .TroubleshootingIf the USB-based deployment fails, a file named usbload_error.txt is created on the USB drive with details of the failure .Ensure the USB drive is certified and tested on another Huawei device if it is not recognized .Only one USB flash drive can be connected at a time, and the device must have sufficient storage space for the upgrade files .Post-DeploymentFor security, it is recommended to disable USB deployment after completing the upgrade using the command: set device usb-deployment disable . By following these steps, you can safely and effectively use a USB flash drive to deploy configurations or upgrade firmware on Huawei switches.
